Operation principle:
A. dispense tip:
1.: get into transport 1 like pcb board in (Fig. 2), wait plate to be sent to the conveying mid portion, after the inductor induction
Whole plate mechanism 40Whole pcb board to carrying the middle cross conveying mechanism that is sent to then.
A. whole plate mechanism 40 (Figure 12): the centre that is positioned at transport 1 bottom; After inductor is sensed plate; Lift cylinder withdrawal servo-actuated wheels supporting plate rises to above transporting flat, and whole then board motor action is whole middle to carrying pcb board. and cylinder stretches out the servo-actuated wheels and drops to the end in transporting flat afterwards.Whole plate mechanism 40 by whole board motor 401, servo-actuated wheels lift cylinder 402, guide shaft 403, guide pin bushing 404, synchronizing wheel 405, put in order plate corrosion resistant plate 406, guide rail 407, supporting roller 408, belt 409 and form.
2.: the cross conveying (
Reciprocal 90 degree upsetsClamping plate are sent to coating mechanism):
Be sent to clamping plate mechanism place Deng plate; Clamping plate cylinder holder rubber tire opens; The pressure handle plate is pushed down under the plate entering exhaust hood. and 90 degree (clockwise) upsets of cross mechanism send plate to coating mechanism then. and the bottom is advanced plate more simultaneously; Arrived baffle mechanism place in (Fig. 3) Deng plate, after the induction back carried counter-rotating to deliver to clamping plate mechanism 50 to plate, clamping plate turned over and turn 90 degrees (reverse) and deliver to coating mechanism to plate again.
A. clamping plate mechanism 50 (Figure 13): when pcb board is risen by induction rear plate cylinder in cross is carried, wait the plate exhaust hood that puts in place to descend again and push down pcb board and prevent in the turnover panel process, to drop.Clamping plate mechanism 50 is by fixedly pinch roller aluminium sheet 501, pressing plate cylinder 502, fixation clip aluminum component 503, pinch roller 504 are formed.
3.: coating mechanism: when arriving coating mechanism on the plate; Moving limit coating is organized servo promotion coating wheel and is fitted with motionless limit coating wheel and be coated with; Servo the drawing back of moving limit coating group is coated with wheel after being coated with, and the flexible stamping ink pad of simultaneously motionless coating wheels bottom stretches out, and holds printing ink and do not drip in the cross conveying of bottom. held in the palm back withdrawal stamping ink pad; Cross is carried and is sent on the plate repetitive operation again.
4. the pcb board double spread simultaneously manipulator drop to the clamping plate position, the clamping plate cylinder is opened and is waited plate induction folder position, the back plate that puts in place, clamping plate and coating wheel are with the speed rising again.Traversing again the putting in place of another manipulator decline treated clamping plate simultaneously.Repetitive operation.
B. baking box cooling discharging section:
5.: manipulator send plate to arrive the little chuck of rotary cylinder Unscrew in the big chain clamping plate places (Figure 10), unclamps after plate puts in place, and clip head-clamp plate gets into the baking box baking. the cooling section in (Fig. 1) cools off again. after deliver to the discharging section ejecting plate.
6.: sucker holds pcb board in the discharging section (Fig. 9); Rotary cylinder is opened clip in (back Fig. 8); Cylinder 106 withdrawals; Grab the decline of plate machinery group and break away from clip; Manipulator rotating servo system (111) rotation is put plate simultaneously, and cylinder 103 stretches out and makes manipulator put into the U type groove of conveying. transmit discharging to plate again. and put when fishplate bar is got up in manipulator rotating servo system (111) rotation behind the plate 108 rotations of manipulator rotating servo system and avoided another and organize manipulator. get back to original position fishplate bar more afterwards, repetitive operation.
